Study on process conditions for producing lube base oil from vacuum fractions
The industrial tests were performed on lube base oil production with vacuum cut 2, cut 3, cut 4 and light deasphalted oil from Sandi light crude oil.
No. 1 standard oil for rubber test was formulated by lube base oil from a deep-refining paraffinic crude blended with vacuum side streams.
Progresses in design, techniques and engineering development of domestic residue hydrodesulfurizing unit, hydrocracking unit and lube base oil hydrotreating unit were summarized.
